** Creation of 3 brands i.e. Rajhdhani(1969), Shatabdi(1988), Superfast(1970s) class of trains, were totally justified over the age old existing M/E & Passenger (incl.EMU/MEMU/DEMU) class of trains.
** Since last 3-4 decades, every RM tried to create its own brand on whimsical grounds and become immortal.
** This journey began with creation of Janshatabdi & Sampark Kranti brand of trains, which were supposed to bring faster travel to non ac chaircar, & IISleeper classes. This appeared justified at that point of time.

Since then every RM indiscriminately tried to create new brand of trains

** LHB coaches with AC + non AC coaches 130kmph max speed
Yuva- should be converted all ac Rajdhani or SF intercity...

Humsafar- converted into Intercity with enough AC coaches
GR-Intercity with enough AC coaches
ACDD-attaching AC DD coaches to existing trains like Shatabdi, intercity etc trains.
Fully AC Duronto- to be converted into Rajdhani with justified stops
non AC Duronto- Intercity SF
Janshatabdi- should be converted into Shatabdi with LHB coaches.
Sampark Kranti- can be operated with LHB rakes as non ac rajdhani with high priority & aggressive schedules like Rajdhani.

** LHB coaches with only AC coaches 160/200kmph max speed
Rajdhanis/Shatabdies should be using Tejas rake with 160/200kmph rake which will soon be operable on Delhi-Mumbai/HWH routes and later on other trunk routes. Low fare ACDD & ACIII-Econ coaches shall help proliferate such trains.
